The blind estimation technique is useful for an adaptive array antenna, a MIMO communication system and a cognitive wireless communication system. The independent component analysis (ICA) developing in the area of the image processing and the speech processing is a simple algorithm with demand upon less priori knowledge. In this report, it is described that an experiment of the blind signal separation of the microwave mixture signal consisted of two signals with QPSK modulation. The digital wireless communication system with two transmitters and two receivers was setting up to obtain the microwave mixture where a carrier frequency was 2.45GHz. The separated signals from the mixture using the ICA were good agreement with the source signals.
